It was a separate forum within PCA where some 200 members took part in an evaluation test of "Star office". We each received a copy of this program, then set certain task to do over the following week.
Challenging and interesting to do, difficult at times but help from other members taking part was available from the "Star" forum. Very enjoyable. j.
Sorry but all the links went down as the forum was deleted shortly after the tests were completed. There was an article on Star in one of the issues of PCA, based around comments and perceptions of the team of guinea pigs, but I can't remember what issue it was in.
